PHILIP LEV ITT, OF CHICAGO, ILLINOIS.

JOINT.

Application filed August 26, 1915, Serial No. 47,528.

To all whom it may concern Be it known that I, PHILIP Lnvrr'r, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful lm n'ovements in Joints, of which the following is a specification.

This invention relates to closet seats and its object is to provide a simple and durable means of joining the sections forming the seat.

Under present methods closet seat sections are joined either by glue or by bolts or metal plates. But it usually happens that the damp atmosphere sooner or later parts the glued joints or corrodes the bolts or plates so that the seat loses its rigidity and eventually falls apart. This invention is not subject to corroding influence, being fully embedded within the seat; thus, the latter being devoid of exposed metal parts at the joints, will maintain its rigidity for a long period.

In the accompanying drawing Figure 1 is a plan view of one of the sections forming the joining device;

Fig. 2 is a bottom view of said section;

Fig. 3 is an edge view of the same;

Fig. 4 is a sectional view of two such sections linked to make the joint;

Fig. 5 is an edge view of two closet seat sections joined by the device; and

Fig. 6 is a horizontal section of the joint taken on line 77 of Fig. 5.

Referring specifically to the drawing 8 denotes one of the sections used for a joint. Said section is in the form of a narrow metal plate, bent on itself at one end as shown at 9. Said bend is parallel to and spaced from the part 8 and is slotted to form a fork 10. Toward the opposite end of the plate on the side facing the fork 10, the plate has a shoulder 11 which extends transversely thereof and is slightly slanted. The shoulder renders the said opposite end of the late double in thickness, as shown at 12. The back of the thickened portion has two lateral recesses 13 divided by a rectangular ridge 1 1. The top of the latter is a continuation of the top of the plate 8 and its outer end is rounded, as shown. at 15.

When two sections as that described above are superposed in reversed and symmetrical relation they will appear, when extended, as in Fig. 4. The ridge 14 of either section will lie between the fork sections of the Specification of Letters Patent.

other section and the two shoulders 11 will meet with a narrow and tapered crevice between them on account of the divergent re lation of the shoulders.

The closet seat sections 16 and 17, which are to be secured by the device are usually fitted together by means of a tongue and groove joint 18. To adapt the sections to the oining device, a narrow rectangular bore 19 is made through the joint of the seat sections from the outer edge of the seat nearly to the inner edge thereof. A similar bore 20 wholly within the sections crosses the bore 19 at right angles. Two small rectangular bores 21 are drilled parallel to the bore 19 from the outer edge of the seat, passing through the bore 20 near its ends, and extending a short distance beyond it.

To make the joint the two seat sections 16 and 17 are placed opposite each other and the assembled sections 8 in the extended position shown in Fig. 4, are inserted in the sections of the bore 20. The bores 21 will now register with the inside of the bends 9 and pins 22 may be driven therethrough, as shown in Fig. 6, to retain the parts 8 within the corresponding seat sections. Vith the parts in this position a flat, tapered wedge 28 is inserted into the bore 19 from the outer edge of the seat; the wedge being advanced, its point will. enter the space between the shoulders 11 of the parts 8 and when the wedge is advanced farther, the shoulders'll will separate and the sections 8 will close in alongside of each other. This will draw the seat sections 16 and 17 firmly together.

It will be noted that the pins 22 and wedge 23 are well sunk into the seat; they may be rendered invisible and immune from water or moisture by filling the exposed portions of the bores 19 and 21 with wood plugs. The plugs, well fitted, will also prevent the pins 22 and wedge 23 from receding and causing looseness in the joint.

While the device is designed more particularly for closet seats, it may also be used to join successive railing or banister sections or other articles requiring a durable end-toend joint.

The pins 22 are made wide to prevent their becoming bent when the joint is being made.

I claim z- 1. A fastening device for joints comprising two members, each of which consists of which is divided longitudinally to form two spaced branches, and said bill extending parallel to one side of the plate in spaced relation therewith, the opposite side of the plate at the end opposite the-aforesaid end having recesses to receive the hook bill branches of the other plate, and the first-mentioned side of the plate having a transverse shoulder which is opposite the shoulder of the other plate, anchoring pins inside the hooks of the plate, and a wedge adapted to be driven between the shoulders of the plates.

2. The combination of two abutting memhers having a recess intersecting the joint thereof longitudinally, and a transverse recess across the oint and intersecting the lirst-n'ientioned recess; of a fastening device for thejoint comprising two interlocking and slidablv connected members mounted in the transverse recess, each of said fastening members consisting of a plate having at one end a hook the bill of which is divided longitudinally to form two spaced branches, and

said bill extending parallel to one side of the plate in spaced relation therewith, the opposite side of the plate at the end opposite the aforesaid end having recesses to receive the hook bill branches of the other plate, and the first-mentioned side of the plate havinga transverse shoulderwhiclris opposite the shoulder of the other plate, said shoulders being spaced, anchoring pins carried by the abuttingmembers and passing through the hooks of the respective plates, and a wedge adapted to be driven along the longitudinal recess into the space between the shoulders to draw the fastening members together.

flo iies of this patent may be obtained for five cents'each, by addressing the Gommissj Washington, I). 6.

3. The combination of two abutting mem- V bers having a recess ntersecting the ]01Ili3 thereof longitudinally, and a transverse recess extending across the oint and lntersecting the first-mentioned recess; of a fastenshoulders being in line withthe longitudinal recess, anchoring means for the respective members passing throughthe hooks thereof,

and a wedge adapted to be driven along the longitudinal recess intothe space between the shoulders for drawing the members together. V

l. A fastening device for joints, comprising two interlocking and slidably connected members extending across the joint and having hooks at their outer ends, andthe contiguous portions of the members having opposite shoulders on the same side as the hooks, anchoring means for the'respective members passing through the hooks thereof,

and a wedge driven between the aforesaid shoulders for drawing the members together.

In testimony whereof I afiix my signature in presence of two witnesses. p 7
